Title: Improvements in apparatus for manufacturing pottery ware
IPC: B28B5/02
Filed: 1936-02-03
Abstract: 471,589. Moulding and jiggering pottery. MILLER, W. J. Feb. 3, 1936, No. 3265. [A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 10, 1936.] [Class 87 (ii)] [Also in Group X] In a machine for manufacturing pottery from plastic clay on absorbent moulds, the moulds are conveyed in irregularly spaced relation and are transferred one at a time to clay feeding mechanism and then to jiggering mechanism, the moulds being finally accumulated on further conveying mechanism whence they are removed by hand. The moulds M are placed by the operator in random manner on the conveyer A which carries them to a transfer frame 4, guides 4a, being provided to position the moulds. The frame 4, carried on pivoted levers 7, is operated by cam 5 to transfer the moulds one at a time above the chuck 8 across a cleaning brush 4b. The chuck, actuated by a cam, raises the mould to the feeding belt 9. A cylindrical clay billet 5 is fed by the belt 9 into a seat 10a and a slice is cut off the end by a wire 12, which is oscillated in a substantially rectangular path by a frame 13 mounted on a shifting pivot 12a and actuated by a crank 16 in unison with the chuck 8 through rod 17. In a modification, Fig. 14, the wire carrying frame 13a is mounted on an eccentric sleeve 13b which has a limited play between screws 13f to produce the backward and forward movements of the wire. The wire 12 may be electrically heated and cleaned by a wiper 13k or air jet 13l. The severed slice is deposited on the mould by a pivoted frame 10 which is released by a pawl 11 actuated by the frame 13 at the end of its stroke. The belt 9 is driven intermittently by a clutch mechanism actuated by the engagement of the crank 16 with a rod 30. The charged mould is lowered on to a seat 42 which transfers it to the shaping position G where it is raised by a chuck into co-operation with a stationary die 47 which spreads the clay on the mould. The die 47 is heated by hot fluid and may have compressed air forced through it while suction is applied to the chuck through pipes 99. In a modification the upper die 47 may be reciprocated vertically by a cam and springs to give a quick release from the clay and the rim of the article may be trimmed by a spring-pressed heated ring 57 round the die 47. The mould is then transferred to the position H where it is raised into co-operation with a profiling tool 60, the mould being rotated in the raised position. Means are provided for permitting the tool 60 to yield under excess pressure and the tool is adjustably mounted for interchange and to compensate for wear. A groove 83a is provided in the face of the tool 60 to remove excess clay. At the end of the profiling operation a trimming tool 86 is moved into engagement with the rim of the article by the movement of the transfer device E. Various forms of profiling tools are described. The mould is finally lowered and transferred on to the conveyer B from which it may be removed to a dryer.

Abstract: 930,528. Packaging. AKERLUND & RAUSING A.B. Jan. 30, 1962, No. 3484/62. Class 94(1). Non-aired roasted and ground coffee or other inert gas emitting foodstuff is loaded into containers 3, 4 which may be evacuated by the vacuum pump 24<SP>1</SP> and then recharged at a pressure above atmospheric from a carbondioxide source 29 through appropriate cocks and reducing valves. The material is then fed to a hopper 9 by feeders 30 or 31, the level in the hopper being controlled by the agitator blade 32 which makes contact with the ring 33 thus completing or interrupting the electricity supply to the feeder 30 or 31. The plate valve 7 determines which container 3 or 4 is connected to the hopper 9. The screw conveyer 11 then discharges the material into the tube formed by the shaping plate 14 from the web 15 which is longitudinally sealed by the heater 13, the container 41 being supplied from the source 29 through the reducing valve 42 to maintain an over-pressure. Just before the longitudinally movable sealing jaws 52, 53 close the package 54 it is momentarily connected via the nozzle 47 to the vacuum reservoir 49 to reduce the interior volume of the package. This allows subsequent expansion of of the package due to deliberation of gases from the packaged material. The carbon dioxide source 29 is also connected via pipes 38, 39 with the hopper 9 and the tube 13, the valve 36 controlling the latter being electrically operated by means of a cam 51 on the packaging machine so that the valve 36 is shut when the valve 48 opens and vice versa. The package formed has its sealing line 57 preferably curved as at 57a or 57b to relieve the strain at the outside edge of the package at the seal.

Abstract: 637,515. Re-vaporizing liquefied gases. WILDHACK, W. A. Feb. 7, 1947, No. 3681. Convention date, Feb. 13, 1946. [Classes 8(ii) and 102(ii)] In an oxygen converter of the kind in which an evaporator operating on a manually or automatically controlled cycle serves to build up pressure of gas over the liquid by the return of a heated and vaporized portion of liquid taken from the container, the liquid portion is forced by the initial pressure in the container S, Fig. 1, through a duct A and a one-way valve D into a reservoir E and is returned as vapour through a different duct Q provided with a one-way valve F, each such cycle of operations being dependent on the opening and closing of air reservoir outlet, e.g. a pressure responsive valve C or a manual valve B. To start pressure buildup within the container sufficiently to force liquid up the duct A and through a main evaporator I to a gas delivery cock H, the manual valve B is opened whereon residual pressure forces liquid up the tube A past the valve D into the evaporator reservoir E which overflows into a flash evaporator G. The resulting pressure rise closes the valve C and opens the valve F to allow passage of the resulting gas to the container S. In a modification the flash evaporator G, Fig. 2, forces liquid from the reservoir E up a tube U and through an evaporating coil P past the valve F to the container S, and a portion of the liquid forced past the valve D passes along a duct R past a manual valve M and a check valve O to flow reverse way through the evaporator I, the resulting warm gas passing down the tube A to bubble through and warm the liquid in the container S. Specification 637,514 is referred to.
